My company is looking to replace JIRA. We use Kanban. Has anyone had experience with this or other products that you'd recommend for a Kanban workflow?
You can combine Kanban with scrum if needed.
Edit: and here is the link (https://tree.taiga.io/support/) that gives more information about taiga. It is not apparent from their website that you can host it yourself for free.

It is basic, but has an API and a sort of automation scripting engine and is fully integrated into Teams.
